Workaround:

spec file

require 'dockerspec/infrataster'
require 'fastimage'

Infrataster::Server.define('app', '127.0.0.1')
`find spec/docker-compose -type f -name "*.tpl.yml" | xargs -I% -n1 /bin/bash -c 'envsubst < % > $(dirname %)/$(basename % .tpl.yml).yml'`

docker-compose.tpl.yml:

version: '2'

services:
  images:
    image: nginx:1.10-alpine
    volumes:
       - $PWD/spec/images:/usr/share/nginx/html

@estahn thanks for all your reports :wink:

[zuazo]

I'm going to leave this issue open, but if I understand the problem correctly, this should be fixed in the docker-compose-api gem.

@zuazo

As I can see the docker-compose-api gem has been released today. Could you please take a look. Is issue still actual?

Thanks @sergeyklay.

Unfortunately the error still seems to prevail. But I'm not sure if it is a docker-compose-api or docker-api gem problem.
